Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a radiation detection panel with fluorescent material layer and photodetector is used to achieve high-definition imaging, then image quality and sensitivity are improved, but device complexity and size increase
Solution Approach 1:
The radiation detection device is divided into distinct functional modules: a radiation detection panel with fluorescent material layer for X-ray conversion, a photodetector array for light detection, and a circuit board for signal processing. This segmentation allows each component to be optimized independently while maintaining overall system performance and facilitating modular assembly.
Solution Approach 2:
The patent transitions from conventional 2D planar detection to a three-dimensional stacked architecture where the fluorescent material layer is positioned above the photodetector array. This vertical arrangement enables high-definition imaging capabilities while managing device complexity through spatial optimization.
2Reliability
If a solid detector structure is implemented for stability and image quality, then reliability is improved, but portability and flexibility are reduced
Solution Approach 1:
The radiation detection device incorporates a flexible circuit board that connects the radiation detection panel to the processing system. This dynamic connection allows the solid detector structure to maintain its stability and reliability while enabling portability and adaptability for various diagnostic settings including mobile applications.
Solution Approach 2:
The use of a flexible circuit board as the connection medium between the solid radiation detection panel and the processing system resolves the contradiction between structural stability and portability. The flexible film allows the device to be transported and adapted to different locations while the solid detector maintains its reliability for high-quality imaging.
3Productivity
If real-time moving image detection at 30 frames per second is implemented for fluoroscopic radiation, then productivity is improved, but device complexity and processing requirements increase
Solution Approach 1:
The radiation detection panel performs preliminary conversion of incident X-rays to visible light in the fluorescent material layer before the photodetector array detects the light and converts it to electrical signals. This preliminary action simplifies the subsequent processing required to achieve real-time moving image detection at 30 frames per second by pre-processing the radiation input.
Solution Approach 2:
The patent replaces complex mechanical image processing systems with a photonic conversion system where fluorescent material converts X-rays to visible light, which is then detected by photodetectors and converted to digital signals. This substitution enables high-speed real-time imaging at 30 fps with reduced mechanical complexity.
